STARTS… CARDBOARD

Going into the club “Technical modeling”, we saw a lot of bench models made of paper and cardboard by One of our members suddenly suggested — and in fact the GAK you can build and track racing. Then it will go is available for all thick thick paper or thin cardboard! This material allows to implement all the plans and fantasies in the manufacture of the trace models.
Usually the chassis and body of our guys are made of sheet metal or foil, soldering well-fitting parts. For modelers-beginners this technology is time-consuming and complex that sometimes is a serious obstacle to the manufacture of your little micro-car. For the conditions of the circle in which training in the management of EN-route pay a lot of attention and time, the paper case will be a great help in the acquisition of driving skills. Subsequently, as practice shows, a new chassis and body is very resilient and easily repaired.
Thus it is useful to know, for example, cardboard of the type of EVS thickness of 0.5 mm is about eight times lighter than sheet metal! Therefore, at almost the same strength paper micromachines has considerable reserves in mass. Now we can confidently recommend “paper” technology and other modelers-tracks.
 
Before proceeding to the construction of the hull, you need to prepare the materials and tools. For of blanks is well suited solid thick cardboard box for shoes or other household goods, as well as on cardboard (or presspan). Of the tools you will need a good knife, scissors, ruler, a few templates for curved lines, a compass, a small brush, glue like PVA or “Moment”.
As a prototype of the proposed car racing “Lotus-79” sport class “Formula R1”. On such a machine, famous racing driver Mario Andretti won the world title. For copies of the “Lotus 79” fits popular tracks scale 1.32.
 
Manufacturer start with the power of the inner part of the chassis, the details of which are indicated by positions 1 -18. Work order simple parts chassis copy on preprinted cardboard and cutting out the right parts, they bond.
 
Part of the bottom 1 and sides 2 (see Fig.) together in the first place. Part of the body frame 3,4 and 5 are the box motor Lodge. The dimensions of the parts may be changed depending on the type of the motor. The box in the drawing corresponds to a known engine Japanese made Mabuchi FT-16. Well suited to domestic motor DK-5-19, modified in accordance with the traditions of your mug.
 
To simulate the scale of the air duct channels the chassis elements 2 and 3 of the first unit on both sides of the part 6, 7 and 8. In the front part of the beam 5 stick wall 9, forming a rigid frame for the front suspension.

Pattern details (Rooms meet the requirements of the previous figure).
 
Items 10,11,12 form a box under the front axle. Subsequently, it is pasted on the epoxy tube. The inner diameter corresponds to the front axle (usually 2.5—3 mm). Gluing the front walls 13 completes Assembly of the forward part of the chassis.
 
In the designated place (POS. 17) make a hole to install a strap collector which is widely used on the models in your circle. In the place indicated by the position 14, the tip of a knife cut a hole for a segment of a gear reducer (do not forget that the gear position can be different depending on your engine). In the sides 15 of the punch holes (POS. 18) under the bearings of the rear axle. The bearings are glued in epoxy resin, and sides are supported by angles 16.
 
Wheel and reducer, use those that are tested experience of your fellow club members. Rubber for tires pick up this what is used on the most successful races racing cars. Tyre size, usually 2 mm less than the size of wheel rims.
 
Recommend chassis and drive to put together and test driving performance in the training rounds on the track to correct possible Assembly errors and layout.
The model is based on the parts 19, which are cut hatches of the air duct 20. Valves hatches are folded down. Laterally of the first unit boards 21. Items 22 and 23 form the fairings niches of back wheels. Cockpit the cockpit is curved and glued together from elements 24 and 25. Tail cowl fairing forms item 26. Of the workpiece obtained 27 arc security. In front of the body glued side panels 28 and 29. Of the elements 30 and 31 are about the two piece front wing that stick to the body left and right. From parts 32 and 33 is going to the rear wing and glued to the fairings niches of back wheels. Side fairings rear vision glass 34 is easy to cut from foam or piece of polystyrene.
 
In the cockpit you can install dummy pilots made from foam and paper.
 
The whole upper part of the body is covered several times with nitrocellulose lacquer for priming the surface. After drying Polish the surface slightly cleaned up with fine sandpaper and then painted in accordance with the machine-prototype, or your own. For coloring you can use any nitroemali or synthetic paint for vehicles.
 
With some ingenuity and imagination in this way it is possible to make copies of any of the racing cars “Formula R1”.
